The invention belongs to the technical field of elevators, and particularly relates to a shallow pit safety protection device additionally provided with an elevator, the elevator comprises an elevator shaft, an elevator car installed in the elevator shaft and a pit located at the bottom of the elevator shaft; the safety protection device comprises a mechanical stopping assembly and a telescopic car door toe guard. The mechanical stopping assembly is arranged in the side wall of an elevator shaft and used for limiting an elevator car from entering a pit. The mechanical stopping assembly comprises an executing mechanism, a first safety switch and a controller; the executing mechanism comprises a motor, a connecting shaft and a stopping block. The stopping block is provided with a first position located under an elevator car and a second position located on one side of the elevator car. The telescopic car door toe guard is installed on the front side of the lower end of the elevator car. The car door toe guard is reasonable in structural design, and the pit depth can be controlled within 500 mm by installing the mechanical stopping assembly and the telescopic car door toe guard.
